This is simple trouble shooting, something is stopping the system from being stable, what is it, narrow your options down, well if clock your ram up to 900 and it's stable you know your ram and memory controller is good for it, so next step drop your cpu multi to 6x and crank the fsb to 450, well that puts your chip at 2.7, that's slower than it's rated for, if that's stable you know your ram and board are good for it, then raise the multi and see where you chip caps out.

Now we all know that it's really a mix between them all but you are always best off narrowing it down the best you can, it's exactly how I found out my old P5K-E just wouldn't do over 450FSB on my Q9550 without voltages that were too high to really be safe without cooling upgrades on the chipset.

The fact is that MB is the problem . Look that Quad needs way more power and it just aint getting it . The only thing powering it is a 4 pin power connector and from MY OWN experience a 4 pin power connector on the MB is NOT enough not by a long shot not for a quad core , what is needed is an 8 pin power connector this will deliver the power needed to overclock the CPU . But hey I am just saying this is my personal experience is all .

I wouldn't second guess that at any rate, it's very possible it's not a good board for clocking

The fact of the 4pin connector not being able to supply enough power is silly, it's possible that the mainboard will not draw enough but consider this an 18awg wire @ 12v can easily draw 20+ amps, so unless his cpu is drawing over 240 watts it's not the issue itself. Now they do say there is an unofficial limit of 192 watts on that 4pin plug, still not an issue for this chip.

The changeover from an electronics standpoint was stupid and pointless.

I'm not arguing against your experience by all means, I wouldn't doubt it, but it would be the lack of ability to supply power from the mainboard, not from that being a 4pin vs 8pin.

The 4 pin is capable of 150w, IIRC, a 8-pin is 300w. So the 4-pin shouldn't be the major issue, and in fact I've done plenty of overclocking with a 4-pin(on a board that accepts an 8-pin no less). Now, 4-pin connectors can certainly be an idicator of a poor overclocking board though, usually because they have so few PWM Phases that they can't handle more than 150w, if that.

The problem is once the power gets into the PWM circuits, and is converted and deliveried to the CPU. The 4 Phase setup just can't provide a stable voltage to the CPU under the load of an overclocked quad.

Yes I agree , I had my Q6600 one a 4 pin but I also could not get it past 3.0Ghz stable once I got an 8 pin power connector it went to 3.6GHz .
I am not saying it can not be done but I am saying from what he is stating in his posts it will not be happening unless he gets a MB that can hand out more stable power to the chip is all . But keep tinkering maybe you will get some were . I don't think so but give it a shot .

Hi again.Yea this is a huge difference,I was able to hit 3.8 with all settings on Auto (just Playing),O.K now I'm at 3.6 stable 1.35625v with OCCT .But when I do Intel Burn test I got This: " check the pic " ,even if I drop Vcore to 1.3475.
(I Do not use Turbo V for now ,just bring it for you to take a look ,what I have in my Bios settings)What do I have to do to make it more cooler drop NB or Up Memory. Any suggestion ?
Is this a Top Temp or nothing worry about ???

OK now try taking a small fan put it on your NB like I did . take the NB voltage up to 1.3 or even 1.4 at that time . You should also not need to set the Vcore for this at all . But I will check my bios settings for you and report back to you as there are some settings that you need to set that will give you that boost to get to ( I hope 4.0GHz ) just hold on some ok ?

OK here you are I took pictures of my settings for you . Note that I have the NB voltage set to auto and well my system is stable with this on auto so you may or may not have to set this just yet . But this took Kingston Hyper X RAM this is why I no longer need that voltage on the NB it is really good RAM !

What the speed of your RAM 800 1066 1333 ???
mine is 800?
just wondering .
